IMPROVEMENT IN APPARATUS FOR GRADING PATTERNS.

Specification forming part of Letters Patent No. 219,615, dated September 16, 1879; application filed April 9, 1879.

To all whom it may concern:

Be it known that I, JAMES J. BREACH, of South Weymouth, of the county of Norfolk and State of Massachusetts, have invented a new and useful Machinefor Grading Patterns; and

do hereby declare the same to be described in the followingspecification and represented in the accompanying drawings, of which- Figure 1 is a front elevation, and Fig. 2 a sectional top view, of it. Fig. 3 is a transverse section, and Fig. 4 is a longitudinal-section, of it, taken through the pattern.

By means of the said machine a shoe sole or upper may be graded, or, in other words, be cut from. or marked out on a sheet of leather or other suitable material, so as to be of a size varying from a pattern in length or width, or in both length and width, as occasion may require, such machine being automatic in character, and having toit the following elements or instrumentalities in combination, and to operate substantially as described and represented-that is to say, it has, first, a stationary pattern; second, a tracer and its carrier; third, mechanism for guiding the. tracer carrier around the pattern fourth, mechanism for moving the tracer-carrier around the pattern; fifth, a table or platform for supporting the material to be cut or marked sixth, aprimary carriage adapted to move rectilinearly an d transversely over both the work-platform and the pattern; seventh, two secondary slides or carriages, so adapted to the primary carriage as to be oapable of sliding rectilinearly thereon in a direction longitudinally of it,.one of such can riages being pivoted to the tracer, and the other carrying or having applied to it a marker or cutter carriage 5 eighth, the said marker or cutter carriage adapted to its supportingcarriage, so as to be capable of moving or sliding thereon or therein in directions transversely of the primary carriage ninth, mechanism,substantially as described, applied to the aforesaid carriages for imparting to that of the marker or cutter, from the movements of the tracer carriage, the necessary movements of suchmarker or cutter carriage to cause the marker or cutter to mark or cut a figure or copy, either corresponding in size or shape with the pattern, or varying in length or width, or in both length. and width,relamachine, having within it a stationary horizontal plate, B, above which is the pattern 0,

such pattern being supported by two vertical.

posts, a a. The plate has an endless guide slot, 12, made in it parallel to the edge of the pattern. This groove receives one or more guides projecting down from the tracer-carriage D, there being fixed thereto a line or cord, 0, also fastened to the end of an arm, (I, projecting from a vertical shaft, 0. ()n such shaft is a bevel-gear, j, that engages with another such gear, g, fixed on a driving-shaft, h, provided with a grooved pulley, i.

Fig. 5 is a top view of the arm and shaft and its gear, as described. On revolving the driving-shaft the tracer-carriage will be caused to move entirely around the pattern.

The tracer 7c, carried by the carriage D, is forced up to the edge of the pattern by a spring, 1, suitably applied; and said tracer, at top, is pivoted to the smaller of the two secondary carriages E and G, which are supported on,

the primary carriage F. The said primary carriage F, duly sustained so as to move horizontally or rectilinearly over and transversely relatively to the pattern 0 and the work-support platform H, arranged as represented, supports the two carriages E and G, which should be so adapted to such primary carriage as to be capable of sliding upon it, lengthwise of it.

There is applied to the carriage G another carriage, H, termed the marker or cutter carriage, as in some instances it may carry a pencil, stylus, or marker, to mark the outline of the figure to be produced. In the place, however, of such marker, I employ a vertical cutter, I, shaped as shown in Fig. 6, whose inclined edge 1 is its cutting-edge. This cut ter I so apply to a vertical carrier, (1 as to enable it (the cutter) to freely swivel or revolve under such, in order that the cutter may readily adapt itself to its direction of movement on the sheet to be cut by it. The marker-carriage is to be applied so as to move rectilinearly within the carriage G, and in directions at right angles to the path of movement of such carriage Gr.

Furthermore, the cutter-carrier a has pivoted to it and to a crank, m, of a horizontal shaft, n, a connecting-rod, 0, the same being shown particularly in Fig. 7, which is a section of the cutter, its carrier, and the said connecting-rod and crank. The shaft n is supported in bearings 19 p, projecting from the cutter-carriage, and has fixed to it at its rear end a grooved wheel, q, about which and two other such wheels, 1" 8, arranged as shown, A

a crossed endless band, 1?, Works, such band being provided with a band-tightener, a, if necessary. The wheel 1" is fixed on a shaft, a, which carries a grooved wheel, o, about which and another such wheel, w, a second crossed band, 00, is arranged, as shown. The wheel 20 is fixed on an intermediate shaft, y, upon which is another wheel, 2, about which and the driving-pulley t a third crossed band, a, is disposed, all being arranged as represented.

' On revolving the driving-pulley rotary motion will be imparted to the shaft a, whereby reciprocating vertical movements will be given to the cutter.

There is pivoted to the carriage E one of two radius-rods, K L, the other of themviz.,

' that marked L-bein g suitably pivoted to the carriage G, their pivotal points being shown at b c. The radius-rod K extends through and slides in the head of a pivot, d, which turns horizontally in an adjustable slide, 6, adapted to slide upon a cross-bar, f, and provided with a screw, g, to clamp it to the bar. Such bar f extends across and is fastened to the primary carriage. The other radius-rod, L, is also similarly applied to a stationary bar or rod, h, arranged as shown, and supported by a stationary arm, 71, the adjustable pivotal connection being shown at 7c.

Upon each of the rods f h there is a slide, 6 which is provided with a clamp-screw, m. One of these slides is connected with the carriage G by a bar, a, pivoted to the slide and carriage. The other slide, l", is connected with the cutter-carriage by another bar, 0, pivoted to the slide and to a curved arm extending up from the carriage. (See Fig.8, which is a 1011- gitudinal section of the cutter-carriage, showing the said slide-arm and connection-bar.)

I would remark that the bearings of the op erative shaft of the cutter may be, an d are generally, so applied to the carriage as to be capaable of being moved in a manner to admit of the cutter stock and shaft being raised, so as to draw the cutter upward out of the work as occasion may require, a rotary hook, 1), applied to the carriage, being used to hold down the shaft at other times.

Spanning the work-platform, and pivoted in the standard q, upon which such platform is -fixed, is a bent or U-shaped arm, 1", whose upper part supports a presser, s, which is pivoted to the arm, and has applied to it and the arm a bent lever, t, for raising and depressing it (the said presser) relatively to the work-support table. A wedge forced between the table and the outer arm of the lever may be, and is, usually employed to keep, by means of the lever, the presser down upon the work or sheet of material, in order to preventit, while in the act of being cut by the knife, from revolving on and independently of the platform. The

arm 4 can be revolved horizontally entirely around the table or platform, and will be so moved by the cutter-stock while it may be making its traverse around the presser.

By means of the two radius-rods K L, their I support-bars f h and stationary and adjustable pivots, and the connection-bars n 0, combined with. the stationary arm i, the primary and secondary carriages, and cuttercarriage by devices as set forth, the machine may be adapted to automatically mark or cut a copy of the pattern, varied in length or width, or in both length and width, relatively to the pattern, as may be desirable.

My machine, though in some particulars like that described in the United States Paten-t No. 201,111, differs in others materially therefrom, my said machine having mechanism for operating it automatically, especially the tracer of it, relatively to the pattern, the

tracer of the patented machine having no such mechanism, but being movable by hand about the pattern. Furthermore, I have a cutter and mechanism for reciprocating it vertically, such not being in the patented machine. So, in my machine, both the radius-bars are connected with their stationary bars by adjustable fulcra.

I therefore claim as my invention as lows, viz:

1. An automatic pattern-grading machine havingthe following elements or instrumentalities in combination, and to operate substantially as set forth-that is to say, first, a stationary pattern, O; second, a tracer, 7c, and its carrier D third, mechanism (viz., the plate B, provided with theslot b) for guiding the carrier around the pattern fourth, mech anism for movin g the tracer-carriage around thepattern, such consisting in the line or cord 0, arm (I, shaft 6, gears f g, shaft h, and pulley i fifth, a table or platform, H, for supporting the sheet of material to be marked or cut; sixth, a primary carriage, F, adapted to move rectilinearly and transversely over both the work-platform H and the pattern 0; seventh, two secondary slides or carriages, E and G, so adapted to the primarycarriage as to sliderectilinearly thereon in a direction longitudinally of it, one of such carriages-viz., E--bein g pivoted to the tracer, and the other carrying or having applied to it the marker or cutter carriage; eighth, a marker or cutter carriage, H, adapted to its supporting-carriage G, so as to move or slide in directrons transversely of the primary carriage F; ninth, a cutter, I, or a marker supported by V the said carriage G, or by suitable devices apsary movements to cause the marker or cutter to mark or cut a figure or copy, either corresponding in size or shape with the pattern, or varying in either length or width, or in both, relatively thereto, as occasion may require, such mechanism consisting of the bars f h, radius-rods K L, connection-bars n 0, and their stationary and adjustable pivotal connections, constructed, arranged, and applied essentially as set forth. 7
